  devices.
• It is vital component that hides the underlying
  hardware complexity and heterogeneity and enables
  the construction of software.
• It is similar to the desktop operating system
  with restricted components.

17
Why choose Symbian OS as a development platform?
Because Symbian OS is written in C Clearly
defined APIs allow the large developer
community Symbian C APIs enable extremely
efficient multitasking and memory management.
Symbian OS is primarily event driven rather
than multithreaded, potentially saving several
kilobytes of overhead per thread.
18
How reliable is Symbian OS?

• Preventing memory leaks with effective memory
  management
• Releasing resources as soon as they are no longer
  needed (garbage collector)
• Handling out-of-memory errors properly through an
  effective error-handling framework.

19
Is Symbian OS opensource???

• A common question is whether Symbian OS is
  "open". It is not open in the sense of Open
  Source software - the source code is not publicly
  available.
• Moreover, the APIs are publicly documented and
  anyone can develop software for Symbian OS.
• This contrasts with traditional embedded phone
  operating systems, which typically cannot accept
  any aftermarket software with the exception of
  Java applications.

20
Evolution of Symbian OS (I)

• Psion - In 1980, Psion was founded by David
  Potter.
• Epoc16 - After the failure of the MC400 Psion
  released its Series 3 devices from 1991 to 1998
  which also used the EPOC16 OS, later known as
  SIBO, which supported a simple programming
  language called OPL and an IDE called OVAL.
• EPOC OS Releases 13 - The Series 5 device,
  released in 1997, used the first iterations of
  the EPOC32 OS.
• EPOC Release 4 - Oregon Osaris and Geofox 1 were
  released using ER4.In 1998, Symbian Ltd. was
  formed as a partnership between Ericsson, Nokia,
  Motorola and Psion, to explore the convergence
  between PDAs and mobile phones.
• EPOC Release 5 a.k.a. Symbian OS v5 - Psion
  Series 5mx, Series 7, Psion Revo, Psion Netbook,
  netPad, Ericsson MC218 were released in 1999
  using ER5.

EPOC is a family of operating systems developed
by Psion for portable devices, primarily PDAs
21
Evolution of Symbian OS (II)

• ER5u a.k.a. Symbian OS v5.1
• u Unicode. The first phone, the Ericsson R380
  was released using ER5u in 2000. It was not an
  'open' phone - software could not be installed.
  Notably, a number of never released Psion
  prototypes for next generation PDAs, including a
  Bluetooth Revo successor codenamed Conan were
  using ER5u.
• Symbian OS v6.0 and v6.1 - Sometimes called ER6.
  The first 'open' Symbian OS phone, the Nokia
  9210, was released on 6.0.
• Symbian OS v7.0 and v7.0s - First shipped in
  2003. This is an important Symbian release which
  appeared with all contemporary user interfaces
  including UIQ (Sony Ericsson P800, P900, P910,
  Motorola A925, A1000), Series 80 (Nokia 9300,
  9500), Series 90 (Nokia 7710), S60 (Nokia 6600,
  7310), Psion sold its stake in Symbian.

22
Evolution of Symbian OS (III)

• Symbian OS v8.0
• First shipped in 2004,
• Symbian OS v8.1
• Basically a cleaned-up version of 8.0, this was
  available in 8.1a and 8.1b versions,
• Symbian OS v9.0
• This version was used for internal Symbian
  purposes only. It was deproductised in 2004.
  v9.0.

23
Evolution of Symbian OS (V)

• Symbian OS v9.1
• Released early 2005. It includes many new
  security related features, particularly a
  controversial platform security module
  facilitating mandatory code signing.
• S60 3rd Edition phones have Symbian OS 9.1. Sony
  Ericsson is shipping the M600i based on Symbian
  OS 9.1 and should ship the P990 in Q3 2006.
• The earlier versions had a fatal defect where
  the phone hangs temporarily after the owner sent
  hundreds of SMSes. However, on 13 September 2006,
  Nokia released a small program to fix this
  defect.

24
Evolution of Symbian OS (VI)

• Symbian OS v9.2
• Released Q1 2006. Support for Bluetooth 2.0 (was
  1.2) and OMA Device Management 1.2 (was 1.1.2).
  S60 3rd Edition Feature Pack 1 phones have
  Symbian OS 9.2.
• Symbian OS v9.3
• Released on 12 July 2006. Upgrades include
  native support for Wifi 802.11, HSDPA, Vietnamese
  language support.
• On November 16, 2006, the 100 millionth
  smartphone running the OS was shipped.
• Symbian OS v9.5
• Released in March 2007. Featured up to 25
  reduced RAM usage resulting in better battery
  life thanks to introduction of Demand paging.
  Applications should launch up to 75 faster. Also
  supports SQL.

UIQ

• UIQ is stylus-based interface (heavily influenced
  by the easy-to-use Palm OS one). The best known
  examples of UIQ devices are the Sony Ericsson
  P800 and P900/P910i, although there are others,
  including the Motorola A920/925/1000.
• The biggest downside of UIQ 2 is that some of the
  benefits of multitasking have been removed by the
  way programs revert to a neutral state when sent
  to the background. So you switch away to check
  your calendar or answer the phone and then have
  to re-open your document and find your place all
  over again. And again.
• UIQ 3 promises to restore proper multitasking,
  thankfully, but this won't be available until the
  Sony Ericsson P990i, W950 and M600 arrive mid to
  late 2006.
